71.30 -111.1 0.57
73.17 -119.1 ????
The peak of day 71 has a shoulder at the razing side, and made the width much wider than usual.
No new or reopened problems were reported in this period
Around 3/9/2001, 19:30, many gradients showed a sharp peak (e.g., see OBA Cone).
Similarly, computed values: OBACONEAVG (OBA CONE AVG TEMP) and OBAAVG (OBA/TFTE TEMP)
displayed a peak with long trailing tails around at the time.
OOBAPWR (OBA COMPUTED TOTAL PWOER) and ELBI (LOAD BUS CURRENT) also displayed a sharp peak at the same time (766.4 for red limit 400, and 93.44 for 89 red limit, respectively).
